Wood ants prefer conifers to broadleaved trees in mixed temperate forests Agric. For. Entomol. (IF 1.885) Pub Date : 2020-12-21 Izabela Sondej; Timo Domisch; Leena Finér; Wojciech Czechowski
Wood ants, species of the subgenus Formica s. str., are one of the most important groups of insects in forest ecosystems due to their high abundance and activity. We assessed the foraging pressure of Formica polyctena and Formica rufa, two dominant wood ant species in the Białowieża Forest. In addition, we compared coniferous and mixed stands in these respects. In mixed stands F. polyctena visited

The structure of temperate yellowjacket communities is affected by land development and loss of forest cover Agric. For. Entomol. (IF 1.885) Pub Date : 2020-12-15 Jessica L. MacLean; Lara van Akker; Brian H. Van Hezewijk
As anthropogenic disturbance continues to encroach on natural areas, it is imperative to establish how this disturbance affects species assemblages. Yellowjackets are important predators of a wide range of arthropods, acting as natural population control in many ecosystems. This study seeks to explore how Vespinae community structure shifts with increasing land development in a temperate North American

Leucoptera coffeella is one of the main coffee pests in the Neotropical region and particularly important in crops cultivated under full sun, as in Brazil. The intensive use of insecticides in the last two decades, including molecules of recent use such as chlorantranilprole, has not been successful in suppressing this pest species. Thus, study aimed to detect insecticide resistance and determine the

Wildflower plantings on fruit farms provide pollen resources and increase nesting by stem nesting bees Agric. For. Entomol. (IF 1.885) Pub Date : 2020-11-09 Kelsey K. Graham; Jacquelyn A. Perkins; Alexandrea Peake; Michael Killewald; Jennifer Zavalnitskaya; Julianna K. Wilson; Rufus Isaacs
Wildflower plantings on farms have been shown to attract foraging wild bees, however, whether these added floral resources increase nesting densities of bees remains largely untested. We placed nest boxes containing natural reeds at 20 fruit farms in Michigan. We then compared nesting densities between farms with and without wildflower plantings and analysed nest provisions to evaluate use of wildflower

Thaumetopoea pityocampa is the most important pine defoliator in the Mediterranean basin. Despite being attacked by a number of natural enemies, populations occur frequently at high density in several areas. Egg parasitism was studied in 27 pine and cedar forests in Algeria, in relation to the host density (tents per tree) and the proportion of forest cover in the landscape. Egg parasitism varied from

Invasive gall‐forming wasps that threaten non‐native plantation‐grown Eucalyptus: diversity and invasion patterns Agric. For. Entomol. (IF 1.885) Pub Date : 2020-09-04 Gudrun Dittrich‐Schröder; Brett P. Hurley; Michael J. Wingfield; Helen F. Nahrung; Bernard Slippers
Gall‐forming hymenopterans of Eucalyptus species are highly successful invaders causing significant damage in non‐native plantation forests. To date, at least 16 of these species have been recorded as invasive eucalypt gall formers, of which less than half are known from Australia where they are thought to be native. About 80% of the species have become invasive only in the last two decades, <10%,

Ips acuminatus (the sharp‐toothed bark beetle, STBB) is currently considered to be one of the most serious pests of Scots pine in many European countries. STBB management is among the most challenging tasks in pine forests; the development of methods for monitoring, predicting and managing outbreaks of this bark beetle is therefore crucial. Pheromone‐baited traps have been widely recommended as a valuable

A warming climate, as predicted under current climate change projections, is likely to influence the population dynamics of many forest insect species. Numerous bark beetle species in both Europe and North America have already responded to a warming climate by significantly expanding their geographical ranges. The aim of the current study was to investigate how populations of bark beetles within stands

The most commonly used method to control insect pests, such as leaf‐cutting ants (LCA) in forest plantations, is the application of chemical insecticides, but their use was forbidden in plantations certified by the Forest Stewardship Council because of their negative effect on the environment. A 5‐year derogation of their prohibition was obtained in 2016 in Argentina, on the condition that forestry

The effect of insect herbivory on seed production of Lupinus nootkatensis, an introduced species in Iceland Agric. For. Entomol. (IF 1.885) Pub Date : 2019-12-17 Brynja Hrafnkelsdottir; Bjarni D. Sigurdsson; Edda S. Oddsdottir; Halldor Sverrisson; Gudmundur Halldorsson
Lupinus nootkatensis is an exotic plant species that has been used for large‐scale sowing all around Iceland for land reclamation of eroded surfaces protected from livestock grazing. Until the early 1990s, L. nootkatensis was free from any significant arthropod herbivory in Iceland, whereas, after 1991, many outbreaks of native insect species, primarily Ceramica pisi and Eupithecia satyrata, have been

The influence of leaf traits and deficit irrigation on insect communities in mature green tomato production Agric. For. Entomol. (IF 1.885) Pub Date : 2019-12-16 Janina Milkereit; C. Scott Stoddard; Danica F. Dito; Amanda K. Hodson
Drought affects many agriculturally important areas, hampering the cultivation of water intensive crops such as tomatoes. Unlike processing tomatoes, deficit irrigation of fresh market tomatoes is not currently practiced. Deficit irrigation could have negative trade‐offs for yield and pest populations by changing plant nutritional values and the microenvironment. The present study compared crop response

Sequence data reflect the introduction pathways of the Sirex woodwasp parasitoid, Ibalia leucospoides (Ibaliidae, Hymenoptera) Agric. For. Entomol. (IF 1.885) Pub Date : 2019-12-16 Brett P. Hurley; Katrin N.E. Fitza; Michael J. Wingfield; Bernard Slippers
The parasitoid wasp Ibalia leucospoides is native to the northern hemisphere and has been introduced to the southern hemisphere as a biological control agent for the invasive woodwasp Sirex noctilio. Two subspecies of the parasitoid, Ibalia leucospoides leucospoides (Palearctic distribution) and Ibalia leucospoides ensiger (Nearctic distribution), were introduced and are reported to have hybridized

Prevalence, damage, management and insecticide resistance of stink bug populations (Hemiptera: Pentatomidae) in commodity crops Agric. For. Entomol. (IF 1.885) Pub Date : 2019-12-15 Daniel R. Sosa‐Gómez; Beatriz S. Corrêa‐Ferreira; Beatriz Kraemer; Amarildo Pasini; Patrícia E. Husch; Carlos E. Delfino Vieira; Cláudia B. Reis Martinez; Ivani O. Negrão Lopes
Pest management of stink bugs (Hemiptera: Pentatomidae) in soybean [Glycine max (L.) Merr.], corn (Zea mays L.) and cotton (Gossypium spp.) agroecosystems has become a major concern in several countries of the Americas. In this review, we report an overview on geographical distribution, injury, damage and methods used to control (plant resistance mechanisms, biological control) the most important stink
